Obviously the My Little Pony footage comes from the '80s television show or perhaps from some of MLP's many direct-to-video/DVD movies. But the dubbing is so good that there are moments when we would swear that LM1313 animated these videos him/herself.

For coming up with the idea of mashing up Dr. Horrible with My Little Pony, LM1313, you deserve an honorary Ph.D. in Horribleness.
